Purpose: Run Pi-hole on Synology with Container Manager while planning port 53, network mode, persistent configuration, router DNS and outage redundancy.
Direct answer: A Pi-hole container can run comfortably on modest hardware, yet a rebooting DiskStation can make clients appear to lose Internet access if it is their only configured DNS resolver.
